Hello Gromacs users: I have a problem with a lipid bilayer, when i watch in

How can i flip it to a correct way? I´m trying with gmx trjconv -f file.gro -s 
file.tpr -n index -o file.gro -pbc whole but nothing happens. In index i use 
option System. What can i do to flip the bilayer? should i use lipid and water 
options in index?
Use the -trans option on the lipids to set a translation equal to half 
the box along the membrane normal.
